World Bank Doing Business: "A high ranking on the ease of doing business index means the regulatory environment is conducive to the operation of business."
What this means for NSA: A low ranking (1,2,3 etc) encourages local and private business, enabling greater functionality and influence, thus a greater role for NSAs. A higher ranking does the opposite. Sub saharan africa as a whole is the least business friendly, and fifth out of seven regions in total reform.

Transparency International Corruption Perception Index: The Transparency International Corruption Perceptions Index ranks countries in terms of the degree to which corruption is perceived to exist among public officials and politicians. It is a composite index, a poll of polls, drawing on corruption-related data from expert and business surveys carried out by a variety of independent and reputable institutions. The CPI reflects views from around the world, including those of experts who are living in the countries evaluated. Transparency International commissions the CPI from Johann Graf Lambsdorff, a university professor based in Passau, Germany.
What this means for NSA: Countries with a low ranking and a high score indicates that criminal or unethical NSA's are likely to have greater influence in a country, and it would be unlikely that smaller businesses, NGO's and ethical NSA's would have influence.

Human Development Index: the measure of life expectancy, literacy, education, and standard of living for countries worldwide. It is a standard means of measuring well-being, especially child welfare. It is used to determine and indicate whether a country is a developed, developing, or underdeveloped country and also to measure the impact of economic policies on quality of life.
What this means for NSA: A country with a low ranking is unlikely to require many social, health and cultural oriented NGOs and NSAs, and a country with a high ranking is highly likely to have many social, health and cultural oriented NGOs.

Reporters Without Borders Press Freedom Index: The index measures freedom of the press in countries and assesses a score indicating the government's pressure (or terrorist group pressure, such as ETA) on press freedom. A high score and ranking indicates higher restraint on press freedom.
What this means for NSA: The media, as a NSA, is highly likely to have greater influence on a country with less restrictions on freedom of the press, except where the media is state controlled. Greater press freedom is also more likely to increase the numbers of different forms of media, which also increases the number of NSAs.

Freedom House: The Freedom in the World survey provides an annual evaluation of the state of global freedom as experienced by individuals. The survey measures freedom—the opportunity to act spontaneously in a variety of fields outside the control of the government and other centers of potential domination—according to two broad categories: political rights and civil liberties. Political rights enable people to participate freely in the political process, including the right to vote freely for distinct alternatives in legitimate elections, compete for public office, join political parties and organizations, and elect representatives who have a decisive impact on public policies and are accountable to the electorate. Civil liberties allow for the freedoms of expression and belief, associational and organizational rights, rule of law, and personal autonomy without interference from the state.
What this means for NSA: Countries with lower scores in the two categories are likely to NSAs that have a larger role and more influence in a state. Countries with higher scores that are partly free or not free are likely to have fewer NSAs, with decreasing influence.

Access Index: it has only 4 countries that are sub saharan africa, I'm throwing this one out.

Global Peace Index: The Global Peace Index is composed of 24 indicators, ranging from a nation’s level of military expenditure to its relations with neighbouring countries and the level of respect for human rights. The index has been tested against a range of potential “drivers” or determinants of peace—including levels of democracy and transparency, education and material wellbeing. The team has used the latest available figures (mainly 2004-06) from a wide range of respected sources, including the International Institute of Strategic Studies, The World Bank, various UN offices and Peace Institutes and the Economist Intelligence Unit. The Global Peace Index is intended to contribute significantly to the public debate on peace.
What this means for NSA: Countries with lower rankings (1,2,3 etc) are more likely to have peaceful NSA's that contribute peacefully to the economy, culture, and politics. Countries with high rankings are more likely to have violent NSAs, such as terrorist groups, paramilitary groups, and criminal organizations.

Global Information Technology Report: The Global Information Technology Report has become a valuable and unique benchmarking tool to determine national ICT strengths and weaknesses, and to evaluate progress. It also highlights the continuing importance of ICT application and development for economic growth.
What this means for NSA: I am not really clear on this one. It may mean that NSA's are likely be more influential in a country with better communications because it allows for their deeds and goals to be spread more quickly and efficiently? I need help on this one.

Economic Freedom Index: The highest form of economic freedom provides an absolute right of property ownership, fully realized freedoms of movement for labor, capital, and goods, and an absolute absence of coercion or constraint of economic liberty beyond the extent necessary for citizens to protect and maintain liberty itself. In other words, individuals are free to work, produce, consume, and invest in any way they please, and that freedom is both protected by the state and unconstrained by the state.
What this means for NSA: A free economy makes it highly likely for NSA (particularly business) to have a greater role and influence in society. This means more influence, and greater numbers of NSA. Countries with little or no economic freedom will mean less NSA's, and more power and influence in the hands of a few NSA (like ethnic groups).

Democracy Index: The Economist Intelligence Unit's democracy index is based on five categories: electoral process and pluralism; civil liberties; the functioning of government; political participation; and political culture. The five categories are interrelated and form a coherent conceptual whole. The condition of having free and fair competitive elections, and satisfying related aspects of political freedom, is clearly the basic requirement of all definitions.
What this means for NSA: Free countries are likely have more and varied NSAs, which will hold greater influence. Repressive countries will have fewer NSAs, which will have disproportionate influence in the state.
